I think it'd be cool, and it would definitely get me looking to buy something that I need.
Its not just AG that doesn't like shipping to HI, or at least for free. Its the same way at many online retailers. "FREE SHIPPING **to the conus".
For me, I buy mostly bulk. Recently i bought 240 16x24 microfibers, 80 something magic erasers, 2-3 5gal jugs of various cleaning products, 20 Megs MF cutting disks, 169oz PERL, a few 1gal Hyper dressings, and more.
When I look to buy I do some research online, compare prices, ask for shipping quotes, and try to negotiate a fair deal. For many things, I just goto pakshack. They've always been more than fair with me. Last year when AG was trying to charge me $41 per 1 gal to ship, I contacted Ranney, ordered it through him and he just threw it onto his next order. I saved, he made money.. we both benefited.
I'm not the kind of person to beg someone for help. If AG wants to start working with us HI guys on shipping, i'll be down to order. Until then, there are others out there that will go above and beyond for you. If any of you guys need any help shoot me a PM.
